Preface

Nearly two years ago the German Development Service (DED) offered me the possibility to assist a technical college in the Philippines.

I had finished my studies in electronic engineering in Germany and had gained several years of working experience in the development of medical electronic equipment and the organization of telecommunication units.

Since I have been assigned with the Don Bosco Technical College, I have been teaching in electronics, computer science, and have been working in the training for instructors.

One of the mayor problems I encountered was the lack of preparation time for the lessons. Many teachers are under steady time pressure because they have to serve two or more jobs in order to earn the adequate income. That gave me the idea to develop a ready-made lesson preparation for teachers.

Based on my experience and also due to the visit of many other schools I edited and compiled this Teaching Aid. I tried to integrate practice and theory which is the best way to provide a solid foundation. I hope this will support the teachers as well as it can improve the quality of classes.
